WMF Function 4 vegetable steamer 20 cm (7.9 in) review

A fixed 20 cm (7.9 in) insert in uncoated Cromargan, 11 cm (4.3 in) deep, stated oven safe to 250 °C (482 °F) and designed to match WMF’s own 20 cm (7.9 in) pots.

What we would actually buy A proper insert rather than a folding compromise. The price is the price of it being rigid and deep.

What you are getting

A fixed 20 cm (7.9 in) insert in uncoated Cromargan 18/10, 11 cm (4.3 in) deep, stated oven safe to 250 °C (482 °F), designed to match WMF’s Function 4 20 cm (7.9 in) pots.

Depth

Eleven centimeters. A folding basket holds a single layer; this holds a meal’s worth. If steaming is something you do weekly rather than occasionally, that is the difference.

The oven figure

250 °C (482 °F), published. It means the insert can be used as a rack or a strainer in an oven as well as a steamer on the hob, which no folding basket offers.

The fit

Matched to WMF’s own 20 cm (7.9 in) pots. It will sit in many others; the rim design is what it was made for, so measure your pot’s inside diameter before ordering.

Availability

On sale at around $120 on the American Amazon store at the time of checking.

What we rate, and what we do not

Strengths

  • Deep — 11 cm (4.3 in) — so it holds a real quantity rather than a single layer
  • Publishes an oven limit, which no other steamer here does
  • Fixed and rigid, so it does not collapse when full

Compromises

  • By far the most expensive steamer in this hub
  • Designed around WMF’s own 20 cm (7.9 in) pots — check yours before ordering
  • Fixed diameter, no adjustment

The questions that come in

Will it fit a non-WMF pot?

WMF states it is for their Function 4 20 cm (7.9 in) pots. A 20 cm (7.9 in) insert will sit in many 20 cm (7.9 in) pots, but the fit is designed around a specific rim — measure before ordering.

Why is depth worth paying for?

A folding basket holds one layer of florets. An 11 cm (4.3 in) insert holds enough vegetables for four, which is the difference between steaming as a habit and steaming as an occasion.

Our score

8.7/ 10

A proper insert rather than a folding compromise. The price is the price of it being rigid and deep.
